When we compare Bitcoin with the best, most used fiat and most reliable currency in the world, the Us dollar it clear show that Bitcoin is on a different level to the Us dollar.
Let me show you why wealthy men like changpeng Zhao(cz), Brian Armstrong, Jed mc Caleb etc can hold billions in Bitcoin without being afraid.
If you are afraid that Bitcoin would go to 10k,ask yourself why they hold billions in Bitcoin.
Don't you think that they had more insight than you will ever have?
It cannot be denied that when someone really understands Bitcoin, they certainly will not feel worried about Bitcoin's condition, even in every era, we certainly have confidence that there will be an era where Bitcoin will rise again, because that is the cycle. And Bitcoin has become an extraordinary thing in the world, not only as a global currency that can be used but also as a very valuable investment.
But unfortunately, not everyone understands and wants to understand this. Fear and worry about Bitcoin being intangible is what makes them withdraw. Moreover, there is a lot of FUD that continues to attack Bitcoin, this makes some people not even want to put their money in Bitcoin. In fact, as the OP said, this worry is normal. But Bitcoin has proven how it can be truly valuable and a promising investment. As long as we invest in Bitcoin, and we can grow it well, then this will be more enjoyable and the results are promising. But don't worry about altcoins that won't necessarily be successful.
